ADJUSTABLE BALL-BEARIN G.

Specification of Letters Patent.

Patented Mar. 8, 1910.

Application filed April 22, 1909. Serial No. 491,422.

To all whomit may concern:

Be it known that I, LOUIS Man, a citizen of the United States, residingat Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements inAdjustable Ball-Bearings, of which the following is a specification.

-ly invention relates to an improved adjustable ball-bearing, the objectof the invention being to provide a ball-bearing, of extremely simpleand inexpensive construction, which can be readily and quickly adjusted,by any one of average intelligence, to take up, or compensate for wear,upon the balls or the bearings.

\Vith these and other objects in view, the invention consists in certainnovel features of construction, and combinations and ar rangements ofparts, as will be more fully hereinafter described and pointed out inthe claim.

In the accompanying drawings, Figure 1, is a view partly in elevationand partly in longitudinal section illustrating my iniprovcments. Fig.2, is a view in longi tudinal sect'ion, and Fig. 3, is a view in crosssection on line 3-3 of Fig. 1.

1 represents a shaft about which a member is adapted to rotate, and heldagainst movement in one direction on the shaft by a collar l. Thisbearing member 2 is provided with a run-way 3 for balls 5, and 6 is myimproved adjustable bearing member, which is also provided with arun-way 7 for the balls 5.

A pin 8 fixed to shaft 1 is located in a recess 9 in the end of member6, which lat, ter is in the form of a sleeve supported on the shaft, andone wall of this recess 9 forms a cam 10 positioned against the pin 8,so that when member 6 is turned in one direction,. the action of the camwall 10, against pin 8, will move the member 2 longitudinally toward theballs 5, and take up or compensate for wear.

A set screw 11 is mounted in member 6 and engages the shaft 1 to lockthe member 2 at any desired adjustment. Pi hen it is desired to adjustthe bearing, this screw 11 is loosened, and the member 6 given apartialrotary movement on shaft 1 until it engages the balls 5 withsufficient pressure, so as to form a perfectly running ball-bearing. Thescrew 11 can then be screwed home and the device will be ready forfurther use, and the bearing will be as effectual as when new.

Various slight changes might be made in the general form and arrangementof parts described without departing from my invention, and hence I. donot restrict myself to the precise details set forth, but considermyself at liberty to make such changes and alterations as fairly fallwithin the spirit and scope of the claim.

Having thus described my invention What I claim as new and desire tosecure by Letters Patent is:

In a device of the character described, the combination with a shaft, ofa device around the shaft and mounted to turn thereon, a collar securedaround said shaft back of said device for preventing movement of of saiddevice longitudinally of the shaft, and said device having a ballrun-way in its face opposite the collar, of a sleeve having a smoothbore mounted on said shaft and having a ball run-way at one end, ballsbetween the run-ways of said sleeve and said first mentioned device,said sleeve having a recess in its end farthest from the balls, forminga cam wall, a pin fixed in the shaft and positioned against the camwall, whereby when said sleeve is turned, the action of the cam wall atthe end of the sleeve against said fixed pin will cause the sleeve tomove longitudinally, said sleeve having a screw threaded opening, and ascrew in said opening engaging the shaft and locking the sleeve againstmovement.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

LOUIS MAU.
